Sounds like powdery mildew. Don't let water hit the plants and pick up all the dead leaves to help get rid of it. Let the soil dry out before watering, and keep your soil airated around the base of the plant.I have an hydrangea that has silver stuff around the edges of the leaves. I looked up diseases and can’t find anything resembling my problem. Will someone please help me.
Thank you
